Audi HU162 Emergency Key Blade

The edge wafers in these locks are an unconventional design, each edge wafer will only correspond with one cut position on only one of the milled edge tracks so the opposing cut position needs to be milled to the reverse depth symbol to allow the key to be inserted completely.

Example 1: A number 2 edge wafer in the 2nd position correlates to a number 2 depth symbol in the 2nd position on its corresponding edge track axis and a number 3 depth symbol in the 2nd position on the opposite edge track axis.

Example 2: A number 4 edge wafer in the 3rd position correlates to a number 4 depth symbol in the 3rd position on its corresponding edge track axis and a number 1 depth symbol in the 3rd position on the opposite edge track axis.
